Specific embodiment
Due to the difference of each manufacturer's production technology, polymer lithium electricity currently on the market is divided into takeup type (Sony, Toshiba
To represent), stacked (TCL, ATL are representative) two kinds of different structures.
Existing laminating machine and lamination principle are all layer-by-layer disks, that is, use a continuous diaphragm, diaphragm is used folded
Piece machine carries out Z-shaped bending, and positive plate and being implanted in diaphragm interlayer for negative electrode tab interval are formed lamination, and this mode works
Although inefficiency, the degree of automation can be improved, but be still difficult to meet efficient production.
Common mentality of designing is to improve the feeding efficiency of diaphragm, that is, using continuous, high speed continuous film feeding, is mentioned
High production capacity.
But traditional method is defective, problem is, after film feeding speed reaches 1 meter per second, since diaphragm has
Certain elasticity, high-speed coiling certainly exist restoring force in the process, cause stress, that is, the lamination after winding, electrode can be wrapped up in
Tightly, buckling phenomena is caused.
For existing defect, protection theme of the invention is as follows:
Exploitation is a kind of soft pack cell and the continuous lamination production line of three diaphragms, and theoretically, efficiency raising should be list
Four times or more of the layer continuous lamination of diaphragm.
